I just upgraded to ubuntu 25.10
(wayland server only, no X translations)
and "standard" (qt gtkit) plots in octave give
opengl_renderer errors, with no points or linesplotted in window.

Switching to gnuplot with graphics_toolkit command,
then plotting something,
then back to qt with same graphics_toolkit command,
and plot works again properly (with qt) !!!!!

Instead, if I just go to gnuplot, then back to qt without
any plots in gnuplot mode, then I still get
the opengl_renderer errors.

Even if it's a workaround, I' d like it to work straight away.

There's some init problem which is correct in gnuplot mode,
not in qt mode, then remains ok when back to qt mode.
